System and method of investment management including means to adjust deposit and loan accounts for inflation

ABSTRACT

Data processing for novel form of relationship management links, supervises, and balances depositors, marketing agents, financial intermediaries, mortgage brokers, and borrowers in an inflation-adjusted financing program. Funds are deposited in participating financial institutions in return for certificates of deposit yielding a fixed rate of interest, plus principal growth at a yearly rate equal to that year&#39;s rate of growth in the Consumer Price Index-All Urban Consumers, All Items. Funds on deposit are loaned to borrower, either directly or through brokers, at a rate calculated by adding three components: a fixed debt service rate, a fixed constant interest rate, and an inflation factor interest rate which reflects the effects of inflation on the outstanding loan balance. Organizing company sychronizes entire program by contacting depositors through marketing agent, designating institutions to receive depositors&#39; funds, contacting borrowers directly or through brokers, and by supplying data processing capabilitites to financial intermediaries for purposes of impletation of the program and for analysis of the effects of the program on the intermediaries&#39; capital structures.

This is a Continuation of application Ser. No. 07/187,054 filed Apr. 27,1988, now abandoned, which in turn is a Continuation of application Ser.No. 770,493, filed Aug. 27, 1985, now U.S. Pat. No. 4,742,457.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to financial management systems and, morespecifically, to data processing methodology for effecting an improvedcapital structure in financial institutions.

2. Description of the Prior Art

A number of financial management systems have been proposed in the past.Exemplary systems include U.S. Pat. Nos. 4,194,242; 4,232,367;4,321,672; 4,346,442 and 4,376,978. However, such prior systems addresssubstantially different problems and accordingly, are substantiallydifferent from the inflation-adjusting program of the present invention.

During times of inflation, lenders and borrowers, whether they beinstitutions or individuals, must anticipate what the effects ofinflation will be on the cash flow characteristics of a loan. Investorsface a similar uncertainty. Traditionally, lenders compensate for thisuncertainty by including a premium in the interest rate charged on theloan. This premium represents what the lender feels will be the level ofinflation during the term of the loan.

Loans which include a fixed inflation compensation factor are not immuneto the effects of inflation. For example, when a lender anticipates a 6%annual inflation over the life of a loan and the actual averageinflation turns out to be 10%, the lender has realized a 4% annual lossin terms of real dollars. In addition, standard-fixed-payments loans("SFPM's") exhibit a progressive decline with time in terms of the flowof real dollars leading to a real-payment forward "tilt" characterizedby a much greater equity accumulation during the early years of anextended loan. Conventional SFPM's are particularly burdensome in aninflationary environment in that they fail to account for appreciationof the mortgaged property.

In an attempt to compensate for such an eventuality, some lenders haveoffered loans or mortgages which include a floating interest factor thatis periodically varied in some manner to compensate for the effects ofinflation. One such alternative mortgage instrument is the adjustablerate mortgage, or "ARM", which allows for periodic adjustment ofpayments to compensate for what the lender feels will be theinflationary effect on the loan during the upcoming period. For example,a typical ARM is indexed to a standard interest rate such as aparticular bank's prime rate or six-month Treasury bill average.However, due to the fact that ARM's still reflect the market's"expectation" of the inflation rate, their inflation premiums may stillnot reflect the actual rate of inflation.

Two mortgage loan instruments which are directly indexed to inflationhave been offered on a limited basis. One such instrument is theprice-level adjusted mortgage, or "PLAM," whose mortgage balance isperiodically adjusted to account for the effects of inflation during theinterval since the previous adjustment. PLAM's have generally beenindexed to one of the various consumer price indexes. Such indexing ofthe PLAM loan balance results in the deferral and capitalization ofadditional interest. The resulting PLAM loan serves to even out equityaccumulation during the life of the mortgage in contrast to SFPM's.

Another indexed mortgage instrument is the "modified" PLAM whichcombines some aspects of the traditional fixed rate mortgage with thoseof the PLAM. In particular, the modified PLAM has a fixed interest ratewhich includes a specified inflation factor and, in addition, has avariable interest rate which will compensate the lender for inflationover and above the specified inflation factor.

Inflation-indexed loan instruments have advantages in that inflationrisk to the lender is minimized. For example, with SFPM's during periodsof inflation, the borrower realizes a windfall in terms of actualdollars where the loan rate is based on a low level of anticipatedinflation. Converselly, the lender has suffered a loss in terms of realdollars. Inflation indexed loans serve to solve this problem. However,the borrower under such instruments still faces much uncertainty: wheninflation spirals, so do the loan payments. If inflation operatessimilarly on the mortgaged or secured property, there is no loss interms of real dollars. However, if the value of the property securingthe loan does not inflate at the same rate as the loan balance, there ispotentially an inflation loss.

Such problems have in the past prevented large-volume or commercialborrowers from taking advantage of inflation-indexed loans. That is, theuncertainty over whether the return on inflation-indexed borrowed fundswhich have been reinvested, will compensate for the "cost" of thosefunds. This problem of unbalanced investments and loans is seen mostaccutely where one wishes to invest in a manner that will assure aninflation-adjusted return on the investment. One answer would be forinstitutions to accept investment capital into deposit accounts whichinsure an inflation-adjusted return on the deposited funds. However, therisk to the lending institution is clear: such inflation-adjusteddeposit accounts must in some manner be backed by inflation-adjusteddollars. Equally important, institutions engaged in lending andborrowing funds require the ability to match funds which have beenobtained on an inflation-indexed basis with some similary indexed fundswhich are lent out. Moreover, such institutions require the ability toassess the impact of inflation-adjusted deposit and loan accounts ontheir capital structure.

Accordingly, the present invention addresses these problems by providinga system for implementing inflation indexed deposit accounts, formatching such accounts with similarly indexed loan accounts and foranticipating the effects of these accounts on the existing capitalstructures of the institution or investor.

SUMMARY OF THE INVENTION

The foregoing and other problems of the prior art are solved by thesystem of the present invention which institutes inflation-adjusteddeposit and loan accounts and matches such accounts to provide animproved capital structure for a financial institution. The systemprojects the impact of inflation-indexed deposit and loan accounts onthe institution's capital structure for preselected or anticipatedinflationary environments. Based on such projections and other generalconsiderations, one of several forms of deposit accounts is selectedaccording to the requisites of the depositor or borrower and those ofthe institution.

As contemplated under the present invention, the accounts arecharacterized by a principal component and an accrual component.Principal component is that proportion of the overall account balanceattributable to the initial cash investment. The accrual componentindicates that proportion of the overall account balance attributable toinflation and fixed interest. The account components are periodicallyenhanced or reduced in a manner specified by the characteristics of theparticular account selected.

The accrual component will generally include both a fixed interestcomponent and a variable interest component with the variable interestcomponent being responsive to the rate of inflation. Responsive to therate of inflation, as used herein, means directly responsive to a marketindicator of prior actual inflation and it is not meant to include themarket's expectation of future inflation. Under one alternative, theprincipal component is enhanced by the variable interest component andthe account retired by retiring the fixed interest component by oneschedule and retiring the principal component by a second schedule.However, the account may be retired by retiring both components over asimilar schedule or by amortization. By varying the manner in which eachrespective component is accrued or retired, the cash flowcharacteristics of the account can be significantly altered to fit therequisites of the individual or institution. Cash flow is defined as theoverall flow of cash units from the account, or a selected accountcomponent, to the account holder who will either be the lender ordepositor, at a specified time.

Since the accrual component of either loan or deposit accounts may beadjusted in response to inflation, they can potentially exhibitunfavorable cash flows. Therefore, it is generally desirable to matchloan accounts with deposit accounts, and further generally desirable tomatch accounts with similar intrinsic cash flow characteristics asspecified by their accrual and retirement features. In this manner, cashflow patterns of the loan account would mirror those of the matcheddeposit account. Thus, during times of inflation, for example, negativecash flows attributable to outgoing retirement payments on depositaccounts will be compensated for by incoming payments on loan accounts.

Once the appropriate form of deposit and loan accounts are selected,matched and placed with the institution, data processing is utilized toservice them during their respective terms. As referred to herein, theaccount term is the time period over which the account is retired or"paid out" to the account holder. The account term is generally dividedinto a plurality of adjustment or iteration periods, however, terms maybe scheduled to include only a single iteration. Servicing includes thedetermination of inflation adjustments to the account balance or,alternatively, the inflation premium due the account holder. Servicingalso includes features which protect the principal or balance of theaccounts from the effects of deflation and reports all bookable incometo holder.

Servicing further includes data processing for retiring and enhancingthe accounts according to their respective terms and schedules.Retirement is meant to include a reduction in the particular accountcomponent and enhancement is meant to include an increase or accrual ofthe particular account component. For example, accrual components may beretired separately from the principal component by selecting separateschedules for each. Thus, for example, the principal may be retiredsemi-anually and the accrual retired annually. Schedules may be selectedwhich adjust particular components by a predetermined amount.Alternatively, account components may be retired by amortization.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The System

Referring now to FIG. 1, there is shown in overall scope an operationalflow chart for implementing the deposit/loan inflation-adjusting systemof the present invention. As therein depicted, the broad aspects of thesystem include an inflation-adjusted deposit account 2, aninflation-adjusted loan account 4, an intermediary institution 6 and anaccount management dataprocessor 8.

In the most basic embodiment of the present invention, the intermediaryinstitution 6 receives deposited funds in deposit accounts 2 and lendsfunds through loan accounts 4. Retirement of these inflation-adjustedaccounts are implemented by account management dataprocessor 8. Suchdata processing services the inflation-adjusting accounts in a number ofways, including the determination of their cash flow characteristics inchanging inflationary environments and determining the anticipatedeffects of inflation on the account balance. Characteristics of theindividual accounts are tailored to meet the needs of the particulardepositor.

However, as illustrated in FIG. 1, the system of the present inventionneed not be limited to the three above mentioned fundamental aspects. Ina preferred embodiment, an organizing company 10 acts as a synchronizerby contacting depositors 12 through intermediary 6 or through amarketing agent 14, for example, a pension fund manager. Depositorcharacteristics are listed on a Deposit Funds Available Data File 16("DFADF"), wherein characteristics listed include a depositoridentifier, the amount of funds available, the term of the account, theduration of the account, the type of account and the account retirementschedule. The amount of funds available is the total amount of fundssought to be deposited by the depositor. The term of the account is thelength of time from the initial deposit until maturity (i.e., when theaccount has been entirely retired). The duration of the account,explained more fully below, is a mathematical expression of when theaverage time-weighted dollar is paid out of the account. The type ofaccount, also explained in greater detail below, represents theparticular accrual and retirement features of the deposit account. Theretirement schedule refers to the timing of the iteration or paybackperiods and may include a predetermined retirement amount whereappropriate.

Characteristics of borrowers 18 are similarly listed in a Loan FundsDesired Data File 20 ("LFDDF"), which includes the amount of fundssought to be borrowed, the term of years for which the funds aredesired, the duration of the loan account, the type of loan account andthe loan account retirement schedule. Additional parameters such ascredit rating of the borrower or capacity of the lenders are generallyincluded in the LFDDF or DFADF. Capacity represents the total funds thelending institution may wish to devote to particular categories of loantransactions, for example, commercial development loans.

Data processing capabilities are supplied for displaying and choosingthe particular inflation-indexed account characteristics and forservicing the accounts once installed. Organizing company 10 may alsoact as a matching agent to receive deposit commitments from depositors12 or marketing agent 14 and place such commitments with intermediary 6that may require inflation-indexed deposit funds to back similarlyindexed mortgage loans. Again, intermediary 6 acts as the actual conduitfor the passage of funds but may rely on organizer 10 to match indexeddeposit contributors with borrowers and/or to service accounts 2,4 oncethey are installed.

Servicing the Accounts

In general, four basic types of accounts, represented by thedesignations Group I, II, III or IV, are contemplated under the presentinvention. These accounts vary in terms of their cash flow, principalrepayment and interest accrual characteristics. They can becharacterized as having a principal component, which initiallyrepresents the sum deposited or loaned, and an accrual component, whichrepresents that portion of the balance that is attributable to theeffects of interest, servicing fees and inflation on the principal.However, the accounts of the present invention may vary in terms of howand to what extent interest accrues, whether the interest is "payed out"or reinvested into the overall account balance, and how the account isretired over a selected term.

In their most basic embodiment, Group I accounts include those accountswherein the fixed-interest and inflation-adjusted interest componentsare retired as they accrue. In Group II accounts, both the fixed andadjustable components are retained as principal and thus add to theoverall account balance. In Group III and IV accounts, the fixedinterest component is payed out as it accrues and the adjustablecomponent is added to account balance. Group III and IV accounts differin that Group IV accounts are retired by amortizing the account balanceat each iteration period whereas Group III accounts are retired by apredetermined portion at each iteration period with the remainingbalance being retired at the final iteration.

Referring to FIG. 2, is shown a flow chart, adaptable to dataprocessing, for servicing what are referred to herein as Group I depositor loan accounts. Group I accounts are characterized by a non-adjustedprincipal which is retired over a series of predetermined intervals oriterations. Alternatively, the principal may be retired in one lump sumpayment at maturity. Because Group I accounts do not have adjustedprincipals, their accrual components are also retired at predeterminedintervals over the life or term of the accounts. As with the principalretirement, the accrual component may be retired in one lump sum paymentat the end of the term. Alternatively, the accrual retirement may bescheduled in a separate fashion from the principal retirement.

Generally, the Group I principal retirement schedule will consist of theretirement of the entire principal at the end of the term of theinstrument. The accrual component, on the other hand, is retired as itaccrues at each iteration period, and does not accumulate or enhance theprincipal. This results in an instrument having cash flows closelyresembling those of a "conventional" certificate of deposit or bond("conventional" referring to payment of a fixed rate of interest) withthe difference that accrual payments will vary with the rate ofinflation. Therefore, the cash flow characteristics of Group I accountscan be characterized generally as low during the term of instrument,with a large payment at the end. However, other principal retirementschedules are possible within the Group I framework, and cash flowscould be accelerated through earlier payments of a portion of theprincipal.

As displayed in the flow diagram of FIG. 2, Group I accounts areserviced by first ascertaining, for example from DFADF or LFDDF, theinitial balance, the fixed interest rate to be paid, the inflation indexat the time of the deposit or loan, the total number of iterations oradjustment periods, and the schedules by which the principal and accrualcomponents are to be retired. Proceeding through the flow diagram, thefirst operator, Ir=Ir-1, serves as a counter to determine the number ofiterations remaining in the scheduled account term. The amount of theprincipal to be retired by cash disbursement to the account holder isdetermined by reference to the schedule. Once the current inflationindex (CPIc) is determined, the level of inflation since the lastreporting period is estimated by consideration of a preselectedinflation index which reflects prior actual inflation. A preferredembodiment of the present invention utilizes the consumer price indexCPI-U, for all items. However, any number of indexes may be successfullyutilized including, but not limited to CPI-W, Producer Price Index, theImplicit Price Deflator for the Gross National Product, or any componentof these price level measures so long as the index reflects some measureof past inflation. The level inflation which has occurred since theprevious iteration period can be determined by the formula: ##EQU1##Where CPIo id the inflation index at the time of the last iteration, orthe initial index if the present iteration is the first.

The account servicing scheme makes the determination as to whetherdeflation has in fact taken place since the previous reporting period oriteration period. This test serves to protect against a possiblenegative cash flow which could result during deflationary periods. Ifdeflation has taken place, no adjustment is made to the balance inresponse to the deflation, rather, deflation credits are stored andsubsequently retired when inflation returns. Deflation credit isaccumulated with deflation credit from prior iteration periods, if any,in the form of cumulative deflation credit ("CDC").

If, alternatively, inflation has occurred during the prior iterationperiod, the cash outflow or disbursement attributable to the effects ofinflation on the account balance is determined by applying the inflationrate to the deposit balance. If the cumulative deflation credit isgreater than the inflation disbursement, the CDC is reduced by thatamount and the accrual disbursement to depositors is determined byapplying the fixed interest rate to the principal.

If the CDC value is less than or equal to the calculated inflationdisbursement factor, the disbursement factor is reduced in porportion tothe CDC, if any, and the CDC set to zero. Accrual repayment isdetermined by applying the fixed interest rate to the balance and addingthe product to the inflation disbursement factor. The account balance isadjusted to reflect both the principal and accrual retirement. Followinga test to determine whether any iteration periods remain, the initialCPI (CPIo) is reset to equal the current CPI (CPIc), to allow forinflation rate determination at the next cycle.

Group II deposit accounts are characterized by a principal componentthat is enhanced by the accrual component. Thus, principal growth isobserved on the one and and the account is retired by retiring only theprincipal. Since all inflation and interest adjustments on the accountserve to enhance the principal, only one schedule of retirement isrequired. Group II accounts will generally demonstrate cash flows whichdo not react as quickly to rising inflation as those of Group Iaccounts. This is due to the fact that the accrual component of Group IIaccounts are not necessarily paid out in their entirety at eachiteration period as in Group I accounts. Rather, the accrual is retainedas principal and retired by a preselected schedule, for example, byretiring a predetermined portion at each iteration period. This resultsin a straight-line reduction of the account balance during the accountterm followed by a lump sum payment of the remaining balance atmaturity. Alternatively, a schedule may be selected where the entireaccount is retired by one lump sum payment at maturity with nointervening retirements.

Referring now to FIG. 3, is shown a flow chart for servicing Group IIaccounts. As with Group I accounts, the parameters of initial accountbalance, fixed interest rate to be charged, the initial inflation index(CPIo), number of iteration periods, and account retirement schedulesare supplied. The amount of principal to be retired is then determinedby reference to the schedule. This amount is disbursed to the accountholder.

The inflation rate is estimated and tested for deflation. If deflationhas taken place, deflation credit is calculated and accumulated. If,alternatively, inflation has occurred, the amount of principaladjustment is determined by determining the product of the inflationrate and the account balance prior to the present retirement. Fixedadjustment is represented by the product of the fixed interest rate andthe balance. When the cumulative deflation credit (CDC) is greater thanthe inflation adjustment for any given iteration period, the CDC isreduced in proportion to the inflation adjustment and the accountbalance adjusted to reflect the principal retirement and enhanced toreflect the fixed adjustment.

Alternatively, when the inflation adjustment is higher than the CDC, theinflation adjustment is reduced in proportion to the CDC and the CDCreset to zero. Balance adjustment is accomplished by reducing thebalance in proportion to the principal repayment and enhanced inproportion to fixed and inflation adjustment. Although under Group IIaccounts, actual cash flow consists of the principal retirement,"bookable" cash flow is represented by both principal retirement andinflation and fixed adjustments to the principal. Thus, this "bookable"inflation adjustment factor is reported to the account holder orborrower for, for example, income tax purposes.

Group III and IV accounts are characterized by an accrual component thatis divided into a fixed interest component and a variable interestcomponent with the variable component being responsive to inflation. Forboth Group III and IV accounts, the fixed interest component may beviewed as a part of the depositor's interest on the balance, and retiredby a preselected schedule over the term of the deposit or byamortization. However, the variable interest component serves to enhancethe principal and therefore represents a deferral and capitalization ofinterest into the principal. Therefore, principal growth is observed.

Group III and IV accounts differ in terms of how their respectiveadjusted principals are retired. In Group III deposits, the principal isretired by a preselected schedule over the term. Alternatively Group IVaccounts have principals which are retired by amortization. FIG. 4 isillustrative of the mechanics of Group IV accounts. As depicted therein,Group IV accounts are serviced by first determining the preliminaryseries of variables: the amount of the initial deposit, the fixedinterest rate to be paid, the inflation index at the time of the deposit(CPIo), the total number of iterations or adjustment periods (Ir) andthe retirement schedule.

Proceeding through the flow chart of FIG. 4, as with the previousaccounts the first operator counts the number of iterations remaining inthe scheduled account term. The account balance amortization iscalculated to determine that portion of the principal to be retired atthat iteration period. In particular, amortization of the balance isachieved using the formula: ##EQU2## where:

R is the payment due the account holder;

A is the amount of the balance to be amortized; and

PVIF is defined as ##EQU3## where N is the number of iteration periodsremaining+1, and i is the fixed interest rate

The fixed interest component is calculated by applying the fixedinterest rate to the account balance. Once determined, fixed interestcomponent is generally retired during the present iteration bydisbursement to the account holder. Alternatively, the fixed componentmay be withheld for later retirement, depending upon the requirements ofthe particular schedule.

The inflation rate is estimated and tested for deflation. With Group IVaccounts, during times of deflation, one would expect a diminishment ofthe balance in proportion to the resultant increase in "real" dollars ondeposit. However, the present system avoids this diminishment by storingdeflationary units in the form of deflation credit. As with theforegoing account groups, deflation credit is cumulated, reserved andnot applied against the account balance until inflation resumes to asufficient level to counter it.

Thus, when the inflation adjustment is greater than the CDC, the accountbalance is reduced in proportion to the principal retired and enhancedin proportion to the level of inflation. If deflation credit hasaccumulated to a greater extent than the inflation adjustment during theprior iteration period, the balance is reduced only in proportion to theprincipal retirement. Once a new balance is established, the iterationcycle is completed by testing whether the present cycle represents thefinal iteration period and, if not, by setting the index level of thepresent cycle equal to the initial index for use in the next cycle.

The flow chart of FIG. 4 may be modified to service Group III accountsby retiring a set proportion or amount of the balance instead ofamortizing the balance. Since such a retirement is of a "preselectedamount," the final iteration may include a lump sum payment of thebalance which remains. That is, the principal retirement of Group IIIaccounts, being a preselected amount, would not necessarily track theinflation adjustments, thus potentially leaving an unretired portion duethe account holder at maturity.

Matching Deposit Accounts with Loan Accounts

During times of high inflation, an inflation--indexed deposit account,standing alone, would present a substantial risk to the capitalstructure of the institution that receives and services them. This isthe result of the fact that more inflated dollars must necessarily bedeposited into the account by the institution at each iteration periodto maintain a constant account balance in terms of real dollars. Toremove this risk, the present invention provides a system for matchingthe foregoing inflation-adjusted deposit accounts with loan accounts.

Referring to FIG. 5, is shown in representative fashion, a flow diagramof the matching process. Investors or Depositors 12 direct DepositAccount Manager 14, for example, a pension fund manager, to file Noticeof Availability 24 ("NA") of funds for inflation-adjusted depositaccounts 2 with organizing company 10. Alternatively, those investors 26not represented by account manager 14 file NA 24 directly withoriganizing company 10. Similarly, borrowers 18 or loan account managers22, for example, mortgage brokers, file Notice of Demand 28 ("ND") forinflation-adjusted loan funds. Both ND 28 and NA 24 include suchparameters as amount of funds available or demanded term of account,duration of account, and type of account including its proposedschedule. Independent variables such as credit rating of borrower 18,characteristics of project for which funds are sought and underwritingconstraints if any, may be included in the ND 28. Organizing company 10,or alternatively intermediary 6 lists the characteristics on paralleldatabases, DFADF 16 and LFADF 20, representing supply funds and demandfunds, respectively.

Accounts are matched by matching parameters stored in DFADF 16 or LFDDF20 to create a Hierarchical Matching File 30 ("HML"). Parameters of thedemand and supply files 16,20 are thus matched according to hierarchalconsiderations generally including account amount, term and duration asprimary considerations. A plurality of loans may be matched with asingle deposit, or a plurality of deposits with a single loan, in orderto match the overall amounts. In situations where a plurality of loansare matched with a plurality of deposits, the various amounts aretotaled to achieve a total balance match.

Duration is a mathematical expression of when the average time-weighteddollar is either received or paid out of a particular account. Itprovides information concerning the size and timing of the paymentstream or cash flow of the account. Moreover, duration embodies anexpression of the relation of payment or disbursement size toyield-to-maturity of the account. The mathematical expression of theformula is: ##EQU4## Where D=duration, r=yield-to maturity, t=time ofcash flow, m=term and CF₊ =cash flow at time, t.

When this formula is applied for example, to a $1,000standard-fixed-payment deposit account with a five-year term and 12%total annual interest, the calculated duration is 4.04 years. That is,the average time-weighted dollar is paid out at 4.04 years. In general,group I accounts will show greater cash flows early in their termsrelative to group II accounts, therefore group I accounts will oftenhave lower durations than scheduled group II accounts. The duration ofGroup III and IV accounts will generally fall between that of Group Iand II accounts. Therefore, duration is an expression of the averagecash flow of the account. In matching the duration of a loan accountwith that of a deposit account, or in matching the average duration of aplurality of accounts, the cash flows of deposit and loan accounts somatched will compensate for one another, thereby protecting the capitalstructure of the intermediary.

After matching is achieved by the HMF 20, borrowers 18 and depositors12, or their respective account managers 22,14, are notified of thematch and deposit and loan accounts 2,4 are formalized 32 followed bythe transfer of funds 34 to intermediary 6. Accounts will then beserviced by the account management dataprocessor 8.

EXAMPLE I Servicing of Inflation--Adjusted Deposit Accounts

Data processing and post-data processing activities are utilized toservice the Group IV deposit accounts of the present invention byperiodically adjusting the outstanding balance of the account to reflectthe effects of inflation on it.

a. Mechanics of a Typical Group IV Deposit Account

Refering to FIG. 6 is shown a representative example of a hypotheticalGroup IV deposit account in terms of its year-end balance and adjustmentamortization. The deposit account therein depicted assumes an initialbalance of $100, a fixed annual interest rate of 4%, a steady inflationrate 8% (e.g., an 8% steady annual increase in the CPI), a 30-year termwith 30 annual iteration periods, and a schedule which retires the fixedinterest component as it accrues (i.e., annually).

As will be appreciated by those skilled in the art, the deposit accountof the present example is somewhat similar to a 30-year annuity which issupplemented annually with additional annuities to reflect the higherprice level in the economy. Thus, the fixed amortization rate becomes areal interest rate because the depositor also receives additionalinterest equal to the inflation rate multiplied by the account balance.Each iteration period, if there is a positive increase in the CPI,additional inflation interest accrues but it is payable over theremaining term as an additional stream of annuity payments. The depositaccount can be viewed as 30 separate annuities with an original annuityand potentially 29 annual inflation additions.

The depositor's total receipts (including principal and interest) on thedeposit account increase in lock-step with the CPI so that the paymentthe depositor receives is constant in real purchasing power. In thisgraphical presentation the inflation rate is a steady 8% for the entire30-year term of the account so the depositor's payment increases by 8%each year. The deposit balance changes on any distribution date sinceinflation interest is added to the deposit balance and the annuitypayment retires a portion of the existing principal with each iteration.FIG. 7 depicts the total principal and interest payment of thehypothetical account of FIG. 6. As will be appreciated, the payments tothe account holder increase substantially over time. FIG. 8 graphicallydisplays the "bookable" income components of the periodic retirements ofthe hypothetical deposit account. Note that the interest payments on theoriginal deposit decreases in "straight-line" fashion with time, whereasthe bookable accrued inflation adjustment and interest on accruedadjustment peak at approximately year 21 before declining.

b. Comparing The Effects of Anticipated Levels of Inflation on theAccount

The data processing methodology of the present invention may be used tocompare the cash flow characteristics of a particular type of depositaccount for selected or anticipated levels of inflation. For example,Table I, which was generated using the servicing scheme of FIG. 4,numerically displays the cash flow characteristics of the typical GroupIV account of the present example (i.e., it assumes an 8% level ofinflation and a 4% fixed interest rate). Depicted therein are theperiodic (i.e., yearly) bookable inflation adjustment, interest earned,deposit returned (i.e., principal retired), year-end account balance andthe net cash flow.

Table II was also generated using the flow scheme of FIG. 4 and displaysthe cash flow characteristics of the same Group IV account but includingan anticipated inflation rate of 6% instead of 8%. All other variables,including the term, deposit amount and fixed interest rate, are thesame. The comparative cash flows for 8% and 6% inflation are displayedgraphically in FIG. 9. Note

                            **THE BOOKABLE INFLATION ADJUSTMENT FOR THE 30TH YEAR WILL BE ADDED TO TH     OTHER CASH FLOW COMPONENTS AND PAID AT THAT TIME, SO THE FINAL BALANCE        WILL BE 0.

that there is a significant increase in payments in the later years ofthe Group IV account term with 8% when compared to 6% inflation.

Thus, by inserting various anticipated inflation rates into theservicing schemes of the present invention, the effects of inflation onthe resultant cash flows of the account may be ascertained. In thismanner, the effects of such accounts on the capital structure of theaccount holder may be anticipated and both cases prove that thedepositor would receive a stream of payments with constant buying powerat any time in the future regardless of the behavior of inflation.

EXAMPLE II The Partially-Hedged Program

A lending institution, under certain circumstances, may desire to matchan inflation-adjusted deposit account with a standard-fixed-paymentmortgage loan. Under such a "partially-hedged" match, the net cash flowto the institution during periods of lower inflation will be higher thanduring periods of high inflation. That is, the standard-fixed-paymentloan will generate a fixed cash flow whereas the deposit account must besatisfied with the inflation-adjusted dollars.

For example, FIG. 10 displays the buildup of positive cash flow from anoriginal $100 inflation-adjusted Group IV deposit account and astandard-fixed-payment loan program which are tracked for 30 years underthe assumption that the deposits were used to fund 5-year loans at10.5%, payable monthly, with principal amortized in equal semiannualpayments and with net cash flows reinvested immediately on the samebasis. These loan proceeds are compared to the cash obligations on thedeposit account.

These calculations from a simultaneous deposit-loan transaction do notinclude any of the costs of loan administration or the servicing costsof the deposit account, which is minimal with large institutionaldeposits. The servicing fee has been netted out but there is no need todeduct the customary costs of a retail deposit activity from thisspread.

Though the net interest spread is quite large not all of this cash flowneeds to be immediately reflected as income for tax purposes since theinflation adjustment interest must be recognized as an expense foraccounting and tax purposes. The accrual of the interest expense has theeffect of reducing taxable income in the early years of the depositaccount term. The accrual of the inflation adjustment interest to thedeposit account balance is accurately reflected in the intermediaries'deposit liabilities and also in the intermediaries' net worth.

Table III shows both asset and liability balance adjustments through the30-year term on the original $100 deposit and loan as well as the netreturn on assets. Even with only a 10.5% loan fixed rate, the net returnon assets is reasonably high at 1.11% and grows over time. Tables IV andV convey the same information under an assumed loan rate of 11.5% and12.5%, respectively. As one of skill in the art will appreciate, thesehigher loan rates substantially increase the net return on assets.

Interest Rate Risk

The actual net income and return on assets would depend on the spread ofthe loan rate above the cost of funds. The cost of funds in turn dependson the inflation rate. In a fixed rate market with a 10.5% prime rateand less than 4% inflation the spread is quite large and would result ina return on assets of approximately 2.5% if all funds were loaned out atprime.

An acceleration in inflation rates causes financial markets to adjust tohigher inflation rates by increasing interest rates. If a surge ofinflation were to occur this would work to the intermediary's benefit.Since short-term loan rates are highly sensitive to an acceleration ofinflation, revenues should respond immediately whereas the inflationinterest cost accrues but is paid out smoothly over time.

Furthermore, the market's response to inflation causes bank loan ratesto increase more than the inflation rate. For example, in 1979 wheninflation rates peaked out at 13%, prime reached 21% which would havesubstantially increased the bank's cash flows and after tax spreads.Acceleration of inflation and interest rates insulates the commercialbank from the payment shock of higher money market CD rates and widensthe spread.

Generally with high interest rates and tight monetary policy there is ayield curve inversion in which short-term rates exceed long-term rates.This too would open enormous profit opportunities for the commercialintermediary since the inflation-adjusted deposit funds are borrowedlong and lent short.

The more significant risk to the commercial intermediary is from areduction of inflation and interest rates. This, however, presents nospecial difficulties because the inflation interest is scaled down tothe actual inflation rate. From the lending side lower

inflation rates do tend to lower interest rates but not quite one forone, as sceptical lenders demand inflation risk premiums against thepossibility of renewed future inflation.

If deflation were actually to occur the inflation-adjusted Group IVdeposit account still calls for interest payments based on the fixedamortization rate and deflation results in credits which carry forwardto offset future inflation interest. While the deposit rate at a minimumis equal to the fixed amortization rate of 3.5%, loan rates should besufficient to cover the fixed amortization rate.

EXAMPLE III The Fully-Hedged Program

a. Hedging the Interest Rate Risk

It is possible to fully hedge the inflation interest cost by lendingfunds received by the intermediary in deposit accounts on aninflation-adjusting loan rate basis. An intermediary could, for example,make funds available to coporate borrowers for medium-term corporateneeds of between 3 and 10 years. The present invention provides aninflation-adjusting loan account similar in structure to theinflation-adjusted deposit but, preferrably, with a shorter maturity.Again, the lengthy deferrals on the deposit and the shorter repaymentschedules on the loan allows the intermediary bank to capitalize on thetime value of the more rapid principal repayment on the assets than isneeded to service the liabilities. The return on assets is magnified bythese deferrals.

Such hedging would eliminate real interest rate risk during the term ofthe account having the shortest maturity, but would not achieve a"matched" asset and liability balance for the intermediary. Thisvariation of the hedged program is not fully matched because there aredissimilar terms to maturity of the loan accounts as compared to thedeposit accounts. Thus, when the term of both accounts are dissimilar,some degree of risk will still be present for the intermediary. This isbecause upon renewal of the account having the shorter term, a variationin fixed or "real" interest rates may have developed in the market. Andpotentially, the intermediary could find itself with unbalanced cashflows. The different terms would also leave the intermediary with anunmatched balance sheet. However, it may nevertheless be desirable forintermediaries to hedge inflation-adjusted loan and deposit accountswithout fully matching terms because certain intermediaries may beunable to solicit sufficient numbers of long-term loan accounts withadequate underwriting characteristics to satisfy a fully matchedprogram.

b. The Fully Hedged "Matched" Program

It is also possible to exactly match the inflation-adjusting depositwith an inflation-adjusting loan of equal maturity which would totallyreduce the financial risk from variable inflation rates and yield curveinversions. In this case, the intermediary would be servicing long-termloans, most likely to finance real estate or other durable plant andequipment. With similar maturities of both the loan and depositaccounts, the intermediary can earn a constant spread over its cost ofmoney with matching deposit and loan contracts. This would fully hedgethe real interest rate risk. These loans would also generate substantialfront end fees for the intermediary.

Table VI illustrates the effect on the balance sheet and cash flow of anintermediary when the intermediary takes the excess cash flow generatedby the matched accounts and reinvests this in new loan accounts withsimilar terms to the original account. In contrast to Table III, thereare generally origination fees associated with such long term loans,which would be equal to the arrangement fees charged by the organizer.It can be observed in Table VI that the total net worth generated bysuch a fully matched program would be more advantageous to theintermediary than the total net worth generated by a situation such asdepicited in Table III, in spite of the fact that receipts by theintermediary would be substantially lower in the initial years thanthose generated by the partially hedged programs.

Again, in contrast to the situation of a partially hedged program, theexact match between the loan and the deposit account results inidentical net cash flow and net income, without the need to rely uponthe current tax code in order to generate an additional advantage to theintermediary. The fully matched program will also have in effect ahigher initial return on average assets. It should be pointed out thatTable VI assumes that the income from the loan accounts flows into theintermediary on a monthly basis and the payments due the deposit accountholder must be made on a yearly basis. In this period of time, theintermediary has had the opportunity to invest these funds at the statedfloat investment rate.

Table VII shows the situation under a fully hedged matched programwherein the loan account and deposit account both have an initialbalance of $100 and a term of 30 years. In Table VII, no assumption ismade regarding any reinvestment by the intermediary of the incomeobtained from the loan account. Rather, it demonstrates what the yearlyincome to the intermediary would be before covering the annual servicefee to the organizer under the column titled Spread Retained. Both theloan and deposit accounts have identical values throughout the term ofthe accounts. These values are shown under the column titled AdjustedPrincipal. The cash income generated to the intermediary is shown inTable VII under the column titled ABML Payments. This income has twocomponents: the principal payment and the interest payment. The interestpayment in turn is split into the portion of interest that is passedthrough to the deposit account holder and the portion that is retainedby the intermediary institution shown under the column titled SpreadRetained.

The advantages of such a loan program to the intermediary are futherdepicted in Table VII in the remaining column, where in this case anassumption has been made that a property with a market value of $125 isfinanced by the loan account, and the loan granted by the intermediaryrepresents 80% of the value of such a property. Table VII further makesan assumption that the property increases in value over time in directproportion to inflation and as a result if such a property generatedoperating net income before debt service at a rate of 9.5% of its valuesuch operating income would increase over time also in direct proportionto inflation.

The next column of Table VII titled Loan to Value Ratio shows how eachyear the principal repayment which takes place reduces the loan to valueratio from the initial 80% to levels of 60% by year 11, 40% by year 19,21% by year 25 and essentially 0 by the end of the 30th year. The debtcoverage ratio which is calculated by dividing the net operating incomeof a property by the payments due for debt service thereon is muchhigher than that consistently found in such loans by those skilled inthe art, with a resulting value of 1.49 in the first year whereas theindustry standards usually range between 1.0 and 1.2.

To further emphasize the advantages to the intermediaries, it should bepointed out that this debt coverage ratio of 1.49 is improved insubsequent years to levels of 1.55 by year 14, 1.64 by year 21, 1.75 byyear 27, etc. The last column shows that in terms of "constant dollars,"the payments made by the borrower to service the loan over time areactually reduced from an initial 7.55 to a level of 6.2 by the 30thyear. As the present invention demonstrates, the income paid to thedeposit holder maintains a constant purchasing power, and yet in termsof constant purchasing power the stream of payments that must be made bythe borrower decreases over time.

Tables VIII and IX show the behavior of the loan to value of ratios anddebt coverage ratios over time when the property financed by the loanaccount cannot maintain its value at the same pace as prices increase.Table VIII presents the case of the property appreciating at a rate of1% less than the rate of inflation. In this case, the loan to valueratio is also constantly reduced and the debt coverage ratio no longershows a continuous improvement over time but nevertheless reaches aminimum value of 1.32 in the last year. Yet this is substantially higherthan the norm found in the industry. Table IX shows the case where theproperty fails to keep up with the rate of inflation by 2% per annum. Inthis case, the loan to value rate will initially show a slight increaseand thereafter decreases although at a slower pace. The debt coverageratio in this case decreases at a faster rate and yet by the 30th yearis still higher than 1. This means that the income generated by theproperty will fully cover the cost of debt service associated with theloan at that time.

While matching will reduce the interest rate exposure of theintermediary it will not increase credit risk. In fact, because theborrower's debt service on an inflation-adjusting loan with a 300 basispoint markup is quite modest at 8.25 per $100, there is substantial debtcoverage.

This option is especially attactive to intermediaries that undertakeinterim construction loans on real estate because the long-terminflation-adjusting deposit accounts with its potential to finance along-term inflation-adjusting Mortgage loans would provide permanenttakeout money for the intermediary. This would be true either by designor necessity. In this case the intermediary enters a fully matched-bookprogram on a long-term rather than a short-term basis.

In order to maintain the longevity of the match, the deposit and loanaccount would provide for substantial penalties for early withdrawal andcorresondingly, the loan account would carry a substantial prepaymentpenalty. These penalties do not significantly detract from the appeal ofboth the deposit and loan accounts.
